BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an exercise apparatus that enables a number of exercises to be carried out utilising the arrangement.

2. State of the Art

With the recent trends in exercising many people seek to attend classes such as aerobics or alternatively become a member of a gym where they can attend and regularly exercise. However, these situations rely on an individual being able to attend either a set class or alternatively transport themselves to a gym which may be inconvenient for individuals as it causes them to modify their schedule accordingly. This often results in a situation wherein an individual misses out on their desired exercise routine. Additionally, most exercise apparatus involves a user pushing or pulling against a resistance, for example lifting a weight. However, it is becoming more widely appreciated that exercising in a manner in which exercise is conducted against the weight of the user more beneficial for the fitness and well being of the user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1, an exemplary exercise apparatus. The arrangement comprises a base 102 having supports 104 extending generally perpendicular relative to the base 102. The supports may be height adjustable via a catch mechanism (not shown) whereby depressing a button 106 causes release of a member extending into the upper portion 108 of the support 104 such that the relative height of the upper support 108 to the lower part of the support 104 can be adjusted. This provides adjustability for different sizes and shapes of user. It will be appreciated that any type of mechanism whereby the upper part of the support 104 or in particular the portion at which the user contact member 110 is connected to be height adjustable relative to the base 102. The user contact member if clamped between the upper portion of the support 104. In one embodiment of this aspect of the present invention, a plurality of user contact members are provided which may be releasably connected to the upper support 108. The user contact members are made of a elastically deformable material such as elastic which provided some support to the midriff area of a user for performing exercises such as in particular press-ups. User contact members 110 having different elastic properties can be utilised an releasably connected to the upper supports 108 as necessary. It will be appreciated that user contact members having lower values of elasticity make the exercise easier as more support is provided for the user. This is particularly beneficial for a user who is potentially less fit, or alternatively is recovering from injury. Again, however, a user who is performing an exercise against their own mass rather than against weights or similar thereby improves a user's core stability rather than solely individual muscle groups.

Again referring to FIG. 1, the user contact member in a more preferred embodiment is fixed to one of the upper supports 108 and is drawn across to the opposing upper support 108. A releasable clip mechanism is provided on the opposing support such that the user contact member can be extended to the tension as required. It is clear that increasing the tension in the user contact member 110 will reduce the subsequent elastic property of the user contact member and as such will provide more support to a user. Releasing the user contact member reduces the support provided to the user. The user contact member may extend from one of the supports 108 to the opposing support 108 to extend therethrough and may be clamped via a hinged clip which will clamp the user contact member between two surfaces thereby preventing movement. It will be appreciated that a variety of clamping means may be utilised however provided that the tension in the user contact member is adjustable then the object of the invention will be achieved. It is also envisaged that the user contact member could be used to support a user's back during a sit up exercise. For this reason, it is envisaged that the user contact member may be tilted to provide the devised angle for supporting a user when performing an exercise.

Referring to FIG. 2, a second embodiment of an exercise apparatus is provided of the comprising a user contact member 110 that may or may not be deformable but is arranged to be mounted on a support comprising means to enable the user contact member to move relative to the base 102. The user contact member may comprise a rigid body having a soft covering thereon shaped and configured to receive the generally midriff area of the user to provide support. The support 104 enables the user contact member 110 to move relative to the base and may have a spring 112 or any alternative resilient biasing member which may be deformed when a force is applied to the upper surface of the user contact member 110. If a spring is used as the biasing member, the spring 112 may be removable such that the restoring force against the weight of the user may be altered as required.

A further preferred embodiment of the present invention is shown in particular with respect to FIGS. 3 and 4. Referring to FIGS. 3 and 4, a support onto which the contact member 110 is mounted comprises a biasing means which can be generally referred to as a gas strut or a gas spring. A suitable arrangement is shown in more detail in FIG. 5 but generally comprises a sleeve portion 120 and a piston portion 112 which locates within the sleeve portion 120. It will be appreciated that with reference to FIGS. 3 and 4 the piston portion 122 is arranged to support the user contact member 110 however the arrangement could simply be reversed such that the sleeve 120 supports the user contact member 110 and the piston portion 122 is connected to the base 102. Referring back to the drawings, the piston portion 122 is moveable with respect to the sleeve portion 120 and is moveable against a sealed gas compartment which provides resistance to movement of the piston relative to the sleeve. A sealing arrangement 124 ensures that no gas can escape from the sleeve 122 as the piston portion 122 is forced down into the sleeve 124. It is important in the present invention that there is not an increasing resistance to downward movement as generally downward movement of the piston occurs as would happen with a simple spring arrangement. Accordingly, a valve system (see FIG. 5 for example) ensures that constant resistance through the movement of the piston within the sleeve is maintained. This is important for a user performing an exercise as will ensure that the user does not rely on the increased resistance provided by the biasing means to perform the exercise successfully. Accordingly, a user will be forced to contract their pelvic muscles, for example, in a press up position in order that the user can return to the starting position.

As shown in FIG. 4, protrusions 126 are arranged to extend from the sleeve 120 to enable further exercises to be carried out, for example to provide support for a user's feet for completing a sit up. The protrusions may be fixed to the sleeve 120 via any suitable means, and as can be seen in FIG. 4, the protrusions may comprise a single piece which clamps to the sleeve 120.

Referring to FIG. 5, a suitable gas strut 130 is generally indicated comprising a sleeve 120 and piston 132. The piston moves up and down within the sleeve 132 and the head is provided with a sealing arrangement 134 which prevents release of gas from the chamber 136 out of the system. The head of the piston comprises a protrusion 136 which is arranged such that it will come into contact with the corresponding stopper 138 located at the upper end of the sleeve which acts as a stopper to prevent further movement. When in use, as the piston is forced through the chamber 136 via the weight of the user, movement past the position in which the protrusion 136 contacts the stopper 138 is therefore prevented. An important feature of the present invention is that a valve system 140 is provided which controls the pressure within the chamber 136 such that a constant opposing force is applied against the movement of the piston. This is important as movement of the piston through the chamber 136 will be at a consistent speed (with a constant mass on the piston) and the valve system 140 enables the restoring force to remain substantially constant irrespective of the position of the piston 132 with respect to the sleeve 120. As such, the resistance against movement of the piston 132 through the cylinder 120 will not increase as the protrusion 136 approaches the stopper 138.

It is further appreciated that the pressure within the chamber 136 may be varied as provided for by alternative gas struts currently available. A control or dial may beneficially be provided as indicated in FIG. 3, with reference numeral 118, which can be varied for different user weights, and/or depending on the pressure causes the exercise to be made more difficult as the pressure is lowered, to being easier as the pressure and thus the support increases.

Benefits of the apparatus is significant and enables a user to perform press ups under range of core body weight exercises by providing support in a generally weak pelvic area. The apparatus provides the necessary support to allow the user to get into the anatomically correct position. It also enables the user to slow down the exercise thus enabling the user to perform the right technique and forces the user to contract the pelvic muscles thus ensuring muscle strengthening and continued progress.

The present invention has been described by way of example only and it will be appreciated by a person skilled in the art that variations and modifications may be made to the present invention without departing from the scope of protection afforded by the amended claims. It will also be appreciated that aspects of the invention may be combined to form arrangements having features of both first and second aspects of the present invention. For example, the invention as defined with respect to the first aspect may be combined with one or more features of the invention as described in the second aspect to provide an exercise station.
